How to replace speed sensor?
A good transmission speed sensor is essential to getting peak performance from your ride. Over time, the VSS can wear out like any electronic device. They input vehicle speed data to the transmission control module for shift control and for other systems on the CAN like cruise control and ABS (anti-lock brakes) only to name a few. Most mount directly on the transmission or transaxle case.
They send a varying frequency to a meter in the TCM indicating vehicle speed. The sensors can be mounted either in the transmission case or rear differential assembly. Those in the transmission are typicaly gear driven,.
The speed sensor can send the wrong signals to the computer, which causes the vehicle to idle incorrectly, the transmission to jump gears or the vehicle to rumble heavy. On many vehicles , the speed sensor is located on the rear axle or the transmission case, but on newer model vehicles it is located inside the ABS system.
A wheel speed sensor or vehicle speed sensor (VSS) is a type of tachometer. It usually consists of a toothed ring and pickup. There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. The vehicle speed sensor is used by the transmission computer or TCM to shift the unit.

A vehicle speed sensor (VSS), also known as an output speed sensor (OSS), is what tells your vehicle’s control unit how fast the vehicle is going. Vehicles are equipped with a variety of devices that function together to help the automobile run smoothly.
One of the most important components is the vehicle speed sensor. As the name implies, the function of a speed sensor is to collect information on how fast the vehicle is traveling. One type (engine speed sensor ) is usually installed on the transmission or transaxle, and the other type ( vehicle speed sensor ) is installed on the knuckle arm on the four wheels. The sensor does this by recording how fast the crankshaft of your vehicle is spinning. The transmission speed sensor , also known as a vehicle speed sensor , calculates the gear ratio of the transmission for the engine control unit (ECU).
The VSS generates a signal that increases in frequency proportionate to vehicle speed. The PCM has a base frequency stored in memory for a distance of one mile. By comparing the input and stored value, the PCM calculates vehicle speed.
Speed sensor with mechanical tenon The signal from the rotating drive wheel has a rectangular form.
This vehicle speed sensor is a small magnetic coil that is housed under the transmission on most of the production vehicles today. This sensor is important to your vehicle as it measures the rotations of the gear set in the transmission and relays the information to the instrument panel in your dash. These may include the engine control module (ECM), transmission control module (TCM), cruise control module (CCM), anti-lock brake system module ( ABS ), and instrument cluster module (ICM), to name a few. The speed sensor monitors the transmission rotation and sends this information to the engine computer, which then controls the speedometer appropriately.
Your vehicle comes equipped with a speed sensor. When the speed sensor fails you must replace it for the speedometer to work correctly.
